The Bay of Pigs refers to a failed U.S. invasion of Cuba in 1961. In the early morning of April 14, 1961, a squadron of U.S. B-26 bombers camouflaged with Cuban insignias begin bombarding airports in Cuba in raids that would last for two days, destroying a large portion of the cuban airforce. On April 16, shortly before midnight, U.S. frogmen landed on Cuba's beaches in the Bay of Pigs and set up landing lights to guide the coming invasion. On April 17, 1961, approximately 1,400 anti-Castro Cuban revolutionaries, supported by U.S. Central Intelligence Agency, attempted to invade Cuba. However, this force was quickly overwhelmed when the US didn't deliver promised air and naval support to the operation.
Th Bay of Pigs invasion was an embarrassment to the Kennedy administration and laid the groundwork for a major crisis almost a year later between the U.S. and the Soviet Union called the Cuban missile crisis
